Under the Pharmaceutical Affairs Law in Japan, additive-free is never regulated at present. So here we cannot easily trust universal additive-free products, because that may be from some intention to improve their images.

Pax Naturon Shampoo
400ml 840 yen (Tax in.)

What we commend at this time is not additive-free, however. Taiyo Yushi Corp., which has for over 50 years produced soap products considering mankind and environment, has developed Pax Naturon Shampoo (400 ml, 840 yen) and it is very nice.

That shampoo includes no synthetic surfactant, synthetic antioxidant, coloring and antiseptics that are said wrong to bodies. But they never express additive-free since herb perfume like rosemary, eucalypt or some is used. By the way, the reason why Taiyo Yushi uses perfume is for enjoyers in shampoo aromas.

They recommend acid rinse as Please use Pax Naturon Rinse. So try them together. Under right using, your head would be alright and the way is introduced at their web site.
